IMPROVEMENT IN LAMP-BURNERS.

Spcciiication forming part of Letters Patent No. 37,915, dated March 24, 1863.

To all whom it may concern.-

Be it known that I, JOHN O. BLYTHE, of the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement on Goal- Oil Lamps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this spccication, in Whichi Figurel is a perspective view of the burner. No.2, Fig. 2, is the collar to burner; No. 3, Fig. 3, the tubeplate, with hinge and catch No. 4, Fig. 4, burner complete, attached to lamp.

In Fig. 1, S is the burner; a, the ange turned on at the top; G, the aperture; b., the thread cut on the neck of the burner; (l, slit cut in the saine for hinge to pass through and attach it to the tube-plate l,- c, the slit cut in the lower part of the flange e for the catch m to pass through and hold the burner in its proper place.

In Fig. 2, K K are the lips ot' the collar turned over; h, screw-plate; G, aperture; and F F represent the collar.

ln Fig. 3, o is the tube; l, the tubeplate m, the catch; I), part ot' hinge fastened to the plate; n represents the hinge.

In Fig. 4, S is the burner; G, aperture; a, upper iiange; K K, lips of collar; b, screwthread; F F, collar; h,screwplate; m,catch; n, hinge; e, flange; 0, tube. The burner S has a narrow ilan ge turned on at the top, and another turned up at the bottom, with two apertures cut in the burner for the reception ot' the hinge and catch, as seen in drawings; also, a thread cut on the neck of the burner. The collar has an aperture cut in it to fit on the burner. The edges ofthe collar at the aperture are tiled down to an edge, and it is then screwed down onto the burner (the neck ofto the tube by soldering. The lip or catchl passes up through the aperture cut in the burner, as seen in Fig. 4 at m. The hinge is passed over the flange or rim and through the aperture out in thc'burner at d, as seen in Fig. 1 at d. By this arrangement the burner is securely attached, and can be lifted up for the purpose of trnnniing the wick. The tube is soldered to the screw in the top ofthe lamp, as seen in drawings. The hinge is soldered to the tube-plate, and may be riveted.

Fig. 4: The burner is here complete and atV tached to the lamp. Inside the rim and un. der the hinge, a piece of wire is secured t) give strength to the saine.

By the peculiar combination of the parts I obtain a superior light to any heretofore in vented of this kind-that is, a round tube.

That Iclaiin as my invention, and desire to secure b v Letters Patent, is

The peculiar construction of the burner S, in combination with the collar F F and the tube-plate l l, as combined with it, the tube, and attached to the screw in the top ot' the lamp,as seen in the drawings,or in Fig. No. 4, this burner having no perforations in its sides or wire-cloth, and rising above the co]- lar and having a narrow flange turned over at the top, with screw cut upon it, as substantially described and set forth.

JOHN O. BLYTHE.
